“…The lowest C-organic value is found in cocoa vegetation, in cocoa sample 2 at a depth of 10-20 cm with a C-organic value of 0.40% belonging to the very low criteria and the highest C-organic value is found in Shrub 1 vegetation at a depth of 10-20 cm has a C-organic value of 2.07% with medium criteriaThe conversion of forest land to agricultural land is one of the causes of decreasing organic C levels, soil degradation due to rainwater erosion and low amounts of organic matter in the soil. This is in accordance with [15], which shows that the conversion of forest land to agricultural land and cocoa significantly reduces soil organic C content. The decrease in soil organic C levels occurred because land clearing was carried out using a slash and burn system.…”

The Bilah Sub-Watershed area includes areas that have somewhat critical or semi-critical land so that land use is the result of human efforts in managing the available resources to meet their various needs. This often results in land use not being in accordance with its capabilities. This research aims to examine the chemical properties of several vegetation in Negeri Lama Seberang Village, Bilah Hilir District, Labuhanbatu Regency. The research was carried out from December to March 2024 using a survey method. Soil samples were taken at 3 points for each vegetation and different slopes at depths of 1-10 cm and 10-20 cm using a simple random method. The soil parameters measured were soil acidity (electrometry), soil organic carbon content (Walkley and Black), and soil texture (bouyoucos hydrometer). Soil analysis was carried out at the Laboratory of the Faculty of Agriculture, University of North Sumatra. The results of this research show that on a slope of 0-8% the average soil pH value is 4.61% and organic C is 1.04%, while on a slope of 8-15% the average soil pH value is 4.46% and C -organic 0.91%. On a slope of 0-8% the average value of the clay fraction is 20.27%, the dust fraction is 15.02% and the sand fraction is 64.41%, while on a slope of 8-15% the average value of the clay fraction is 27.48%, the dust fraction 19.87%, and sand fraction 52.63%.

“…Soaking seeds with water might in some way resemble the environmental condition of flooding stress. Indeed, it has been reported that hydropriming can improve the ability of rice seeds to withstand the deleterious effects of flooding, by shortening the emergence time ( Mulbah and Adjetey, 2018 ; Sarkar, 2020 ). Flooding-tolerant seeds are also desirable products for breeding in legumes ( Sayama et al, 2009 ).…”

Hydropriming Applied on Fast Germinating Solanum villosum Miller Seeds: Impact on Pre-germinative Metabolism

et al. 2021

Seed priming can circumvent poor germination rate and uniformity, frequently reported in eggplant (Solanum melongena L.) and its crop wild relatives (CWRs). However, there is still a gap of knowledge on how these treatments impact the pre-germinative metabolism in a genotype- and/or species-dependent manner. The CWR Solanum villosum Miller (hairy nightshade) investigated in this study showed a quite unique profile of fast germination. Although this accelerated germination profile would not apparently require further improvement, we wanted to test whether priming would still be able to impact the pre-germinative metabolism, eventually disclosing the predominant contribution of specific antioxidant components. Hydropriming followed by dry-back resulted in synchronized germination, as revealed by the lowest MGR (Mean Germination Rate) and U (Uncertainty) values, compared to unprimed seeds. No significant changes in ROS (reactive oxygen species) were observed throughout the treatment. Increased tocopherols levels were detected at 2 h of hydropriming whereas, overall, a low lipid peroxidation was evidenced by the malondialdehyde (MDA) assay. Hydropriming resulted in enhanced accumulation of the naturally occurring antioxidant phenolic compounds chlorogenic acid and iso-orientin, found in the dry seeds and ex novo accumulation of rutin. The dynamic changes of the pre-germinative metabolism induced by hydropriming are discussed in view of future applications that might boost the use of eggplant CWRs for breeding, upon upgrade mediated by seed technology.

“…Farooq et al (2006) reported that seed priming was not only enhanced seedling establishment, growth, and yield; but also improved quality of directseeded rice. Seed priming also improved tolerance of plant to biotic and abiotic stresses by accelerating seedling establishment under drought (Hussain et al 2017) and submerged condition treatment (Sulaiman et al 2016;Mulbah and Adjetey 2018).…”

Cross-ecosystem utilizing primed seeds of upland rice varieties for enriching crop diversity at riparian wetland during dry season

Abstract. Ria RP, Lakitan B, Sulaiman F, Kartika K, Suwignyo RA. 2020. Cross-ecosystem utilizing primed seeds of upland rice varieties for enriching crop diversity at riparian wetland during dry season. Biodiversitas 21: 3008-3017. Cultivation of rice during second growing season at riparian wetlands in Indonesia must deal with drought conditions at reproductive stage. Seed priming can speed up seed emergence and produces vigorous seedlings. Objective of this study was to screen upland rice varieties which were positively responded to seed priming and tolerant to drought during late vegetative and/or reproductive stage. Results of this study indicated that osmo-priming showed positive effects on seed emergence, percentage of germinated seed, and time to reach 50% germination. Effects of osmo-priming on seedling growth did not go beyond four weeks after seedlings had been transplanted. Among nine varieties screened, Inpago 10 exhibited better response to seed priming during late vegetative stage as it produced the highest number of tillers and total leaf area. However, at harvest, osmo-priming with 20% PEG lowered filled spikelet and weight of 100 grains but did not affect yield. Drought during late vegetative stage lessened number of tillers but after drought-treated plants recovered during reproductive stage, percentage of filled spikelet and grain size were comparable to those of control plants. Meanwhile, drought imposed during reproductive stage decreased percentage of filled spikelet and grain yield. Despite its better performance under drought conditions, leaf rolling score was higher during heading stage in Inpago 10. This phenomenon indicated that leaf rolling was not forced by drought, rather it was a quick response of Inpago 10 variety to limit water loss due to transpiration.
